mmc: core: Invent MMC_CAP2_FULL_PWR_CYCLE
MMC_CAP2_FULL_PWR_CYCLE shall be set by host drivers which are able to do a complete power cycle of the card. In the eMMC case that includes both vcc and vccq. This CAP is providing the protocol layer with important information, needed to take optimized decisions during card initialization and in the suspend/resume sequence. MMC_CAP2_POWEROFF_NOTIFY is replaced by MMC_CAP2_FULL_PWR_CYCLE, since it makes sense to use a wider scope for it.
